In addition, it takes a long time and a lot of work to fix the columns with expansion screws. The short use time increases the cost and affects the test efficiency.

[0004] In the i-vista VRU group scenario, the construction fence has low stability and is prone to collapse, so it takes a long time to build and the cost is too high. Summary of the invention

[0005] The purpose of the present invention is to provide an improvement method for the construction fence of the i-vista test to meet the VRU group scenario, so as to solve the problems raised in the above background technology that in the i-vista VRU group scenario, the construction fence has low stability, is easy to collapse, takes a long time to build, and has high cost.

[0006] To achieve the above object, the present invention provides the following technical solution: a method for improving the construction enclosure of a VRU group scene for i-vista testing, and the specific steps of the method for improving the construction enclosure of a VRU group scene for i-vista testing are as follows:

[0008] S2: Fix the spray-painted cloth of the construction enclosure on the connecting frame by means of the connecting frame;

[0009] S3: Place the fixed construction fences in the position required by regulations.

[0010] Preferably, in step S1, the pattern display size, edge retention size and pattern to be used of the construction fence are set in advance according to the use requirements;

[0011] Based on the above requirements, the printing cloth substrate is sprayed and formed, and the printing cloth substrate can be cut later.

[0012] Preferably, the connecting frame includes a vertical frame and an inclined supporting frame arranged at the rear side of the vertical frame.

[0013] Preferably, the upright frame includes three upper, middle and lower cross beams and vertical beams connected to both ends of the cross beams, and the upper end of the inclined support frame is connected to the upper cross beam.

[0014] Preferably, the angle between the oblique support frame and the vertical frame is 30°-60°.

[0015] Preferably, a counterweight is provided at the bottom end of the inclined support frame.

[0016] Preferably, the horizontal beam and the vertical beam are provided with connecting hooks on the side facing away from the oblique support frame, and the horizontal beam and the vertical beam are connected to the inkjet printing cloth through the connecting hooks.

[0017] Preferably, the horizontal beam and the vertical beam are provided with a Velcro surface on the side facing away from the oblique support frame, and the Velcro hook surface is provided at the corresponding position on the spray-painted cloth, and the horizontal beam and the vertical beam are connected to the spray-painted cloth via the Velcro surface and the Velcro hook surface.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] During actual use, the painted wall did not interfere with the recognition of the vehicle-mounted perception sensors, and played the role of shielding the wall in accordance with regulatory requirements.

[0020] The construction fence is displayed by spray painting to meet the regulatory requirements. It greatly improves efficiency and reduces cost expenditure. After being fixed, it is not easy to be blown down by strong winds, and it takes less time to build, with low labor and material costs, and can be reused sustainably.
